TL;DR: Armory incorrectly showing 0.00 balance when there is money in the wallet.  How to resolve?

=========

My Armory client wouldn't startup correctly and kept crashing: http://i.imgur.com/EkGOhuq.png
So I deleted the following files from the databases\leveldb_blkdata\ folder and restarted the client:

CURRENT
LOCK
LOG
LOG.old
MANIFEST-019725

It scanned and rebuilt the databases but then instead of showing the full balance for my BTC address only showed the most recent inbound transaction according to https://blockchain.info. My wallet is new, as in the last 2 months.  So even though it scans the blockchain for transactions related to my BTC address Armory is somehow not doing so correctly.  I repeated the steps above and now it shows a zero balance across all addresses.  Seems to me that this software is hugely buggy and can't be relied upon.

Thing's I've done to troubleshoot:
- Rescan databases
- Rebuild & Rescan databases
- Re-downloaded & reinstalled Armory client
- Started Armory client in offline mode and 'revert all settings'

Now ever since 'reverting all settings' the Armory client consistently crashes every time it scans the transaction history.
Deleting everything, including the blockchain, and starting from scratch is really something I'd like to avoid, considering the heavy amount of bandwidth and time required to do so.

Anybody have any ideas?  I have a paper wallet backup.
